HISTORY OF METROLOGY

The first steps of humanity have already presented the need of finding units of measurement. Human body itself constituted the basis for the creation of the first metrical system. Some of the first units created were the dactyl, palami and step.

In cases of long-distance measurement, the units were constituted by the distance of stone shot, the distance that covers in one day one pedestrian, the period of the sun, the moon etc. Depending on the circumstances similar units are still used. Despite the common root of most metrical systems, they differed from place to place. Thus we had the parallel growth of many systems that rendered the transactions among populations difficult.

In ancient Greece the basic unit of measurement was foot. The size was not constant but depended on the point where the measurement was made. Subdivision of foot was the dactyl.

Basic unit of measurement of weight was the obol. The following units derived from the obol are: drachma, mina and talent. Similar units of measurement were also used by other ancient cultures. In Egypt the most famous unit of length was the royal pechys. Its basic subdivision was the dactyl. Meters of liquids were the ro, hekat, har and cubic pechys.

In Babylonia the most famous unit of length was the Babylonian dactyl. Meter of liquids was the ka. The most ancient of all known weights was mina. The Romans adopted the Greek units of measurement changing only the name of some of them.

In earlier periods of middle Ages the use of Roman system of measurement was extended through all Europe and converted from place to place depending on local needs. This resulted in creating lots of different metric systems.
Nevertheless the development of metrical systems was not the expected one. In the 9th century scientists tried to impose uniformity between the various metrical systems but their effort failed.

During the years due to the growth of societies measurements became more complex, while mathematics allowed the creation of specialized metrical units suitable for commercial and scientific use.

Finally the increase of commercial transactions among populations made obvious the need for existence of less metrical systems, which resulted in the predominance of two systems of units nowadays – English and International. Such countries as Britain and its colonies use the English system of measurements. The International system is widespread worldwide.

METROLOGY

Metrology derives from Greek “metron” – measure and “logos” – science. Metrology is the science of measurement. Measurements come in different forms. Gemstones can be measured for hardness or carat size. Pieces of wood can be measured for length. Electricity can be measured in amps, volts and watts. Metrology includes all theoretical and practical aspects of measurement.

In 1950s it was necessary to bring unity to measurement in the manufacturing process. As a result, the International Organization of Legal Metrology was created. Today dozens of countries are members of this organization. Their common goal is to unify manufacturing and business throughout the world.

Metrology is defined by the International Bureau of Weights and Measures, as the science of measurement, embracing both experiment and theoretical determinations at any level in any field of science and technology. Metrology is a very broad field and may be divided into three subfields:

Scientific or fundamental metrology concerns the establishment of measurement units, unit systems and the development of new measurement methods, realization of measurement standards and the transfer of traceability from these standards to users in society.

Applied or industrial metrology concerns the application of measurement science to manufacturing and other processes and their use in society, ensuring the suitability of measurement instruments, their calibration and quality control of measurements.

Legal metrology concerns requirements of measurements and measuring instruments for the protection of health, public safety, environment, enabling taxation, protection of consumers and fair trade.

METRIC SYSTEM

The aspiration of many European scientists for the creation of a new single and uniform metrical system fulfilled at the duration of French Revolution. King Louis the sixteenth (XVI) proposed the creation of a decimal metrical system.

In 1670 Gabriel Mouton, famous scientist, being aware of the fact that this new metrical system should be based on earthly measurement, proposed a decimal metrical system, which would be based on the length of a thin arc of meridian. Later in 1671 Jean Packard, a French astronomer, proposed one unit of length based in pendulum. Nevertheless one century had to pass up to the creation of metric system.

In 1790 the French national assembly assigned to French Academy of Sciences to create immutable models for all the meters and all the weights. The academy created a system of units that was simultaneously simple and scientifically based on the proposal of Gabriel Mouton. In June, 1799 the metric system was adopted.

Finally the basis unit of length – meter was defined. The new units of surface and volume resulted from the meter were the square and cubic meter respectively.

Also as a basic unit of weight was the gram.The gram is equal to the mass of a cubic centimeter of clean water in the temperature of biggest density (4° C) The liter, resulted from the volume of cube with length of each side equal to 10 centimeters.

Multiples of square meter are: the Are, the Acre (10 are) and the hectare (100 are).

Even though the metric system was not accepted with enthusiasm, its adoption from other nations began to increase regularly after its obligatory use in France 1840. It is not accidental that the growth of metrical system coincided with the technological growth in Europe and America.

At the end of 1860 the need for existence of more precise and explicitly determined units became obvious, because of the requirements being created by the new scientific discoveries. This became possible with the Meter Convention in 1875. Meter Convention is an international treaty in which participated 17 countries. 35 nations had officially accepted the metric system.

This treaty determined the units as well as the mechanisms for the constitution and adoption of further determinations in the metric system. The metric models were manufactured and distributed in each nation that ratified the treaty.

The duty of the international office in France is the permanent secretariat of the Treaty of Meter as well as the exchange of information referring to the use and the improvement of metrical system. In 1921 the office extended the work of international standardization in electric models, in 1933 in the models of lighting and in the models of measurement of radiation in 1960.

The same year (1960) a generalized simplification of metric system as well as its denomination in to the International System of Units was decided. The International System of Units has been established worldwide following simultaneously the continuously created scientific needs for the determination of new and more precise metrical units. In Greece the complete establishment of Metric System took place on the 1st of April in 1959 when the unit of weight known as oka was used until then was replaced by the kilogram.

II Read text and define the main idea of it:

SMALL-UNIT METRIC SYSTEM

The small-unit metric system is based on three fundamental units: the centimeter, which quantifies displacement, the gram, which quantifies mass and the second, which quantifies time.

The small-unit metric system is so-called because one centimeter is equal to 0.01 meter (10 -2 m), and one gram is equal to 0.001 kilogram (10 -3 kg). The CGS system, like the metric system, was originally developed by scientists who were frustrated with the English (foot-pound-second) system. The CGS units of displacement and mass lend themselves neatly to calculations in scientific notation, while English units generally do not. Time remains somewhat messy in all systems; there are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day.

The Standard International System of Units has officially supplanted the small-unit metric system as well as the metric system. But it is good to have passing familiarity with the small-unit metric system, because that scheme is still used by some astronomers and physicists, and many older scientific books and papers were written with a preference for it. Today's International System provides formal definitions for the meter, kilogram, second and also specifies and defines four additional units: the Kelvin for temperature, the ampere for electric current, the candela for luminous intensity, and the mole for material quantity.

Other international units are called derived units. There are 22 derived units:

· the radian and steradian for plane and solid angles;

· the Newton for force and the Pascal for pressure;

· the joule for energy and the watt for power;

· the degree Celsius for everyday measurement of temperature;

· units for measurement of electricity: the coulomb (charge), Volt (potential), farad (capacitance), Ohm (resistance), and siemens (conductance);

· units for measurement of magnetism: the Weber (flux), Tesla (flux density), and Henry (inductance);

· the lumen for flux of light and the lux for luminance;

· the hertz for frequency of regular events and the Becquerel for rates of radioactivity;

· the katal, a unit of catalytic activity used in biochemistry.

Each international unit is represented by a symbol. The use of unit symbols is regulated by precise rules. These symbols are the same in every language of the world. However, the names of the units themselves vary in spelling according to national conventions. Therefore, it is correct for Americans to write meter and Germans to write Meter, and it is also correct for the British to write metre, Italians to write metro, and Poles to write metr.

METER

The meter is the international unit of displacement or length. One meter is the distance traveled by a ray of electromagnetic energy through a vacuum in 1/299,792,458 (3.33564095 x 10-9) of a second. The meter was originally defined as one ten-millionth (0.0000001 or 10-7) of the distance, as measured over the earth's surface in a great circle passing through Paris, France, from the geographic North Pole to the equator.

One meter is a little more than three English feet, or about 39.37 inches. One foot is approximately 0.3048 meter. There are about 1609 meters in a statute mile. The official span was at one time formally defined as the separation between two scratches on a platinum bar in Paris. This was, of course, intended mainly for show, and not for use in the laboratory.

In engineering applications and also in an everyday sense, the term meter refers to any instrument used to measure the magnitude of a quantity. Examples include the volume-unit meter in home audio systems, the ammeter to measure electric current, and the kilowatt-hour meter to measure electrical energy consumed over a period of time.

ENGLISH SYSTEM OF UNITS

The English System has its roots in the Roman system, which used as a base the number twelve. Also from the Romans emanated the names of certain English metrical units such as the inch. The English System developed progressively, and in 19th century the English metrical system was established in various parts of the world, including America. At the heart of the English system of Units is a short list of base units:

Units of Weight

The pound (lb) is the basic unit of weight which is proportional to mass. Within the English units of measurement there are three different systems of weights. In the avoirdupois system, the most widely used of the three, the pound is divided into 16 ounces and the ounce into 16 drams. The ton, used to measure large masses, is equal to 2,000 lb. The troy system is used only for precious metals. The troy pound is divided into 12 ounces and the troy ounce into 20 pennyweights or 480 grains. The troy pound is thus 5,760 grains. The grain is also a unit in the avoirdupois system, 1 avoirdupois pound being 7,000 grains, so that the troy pound is 5,760/7,000 of an avoirdupois pound. Apothecaries' weights are based on troy weights.

Units of Length and Area

The basic unit of length is the yard. Fractions of the yard are the inch and the foot and commonly used multiples are the rod, the furlong and the mile. The acre, equal to 4,840 square yards or 160 square rods, is used for measuring land area.

Units of Liquid Measure

For liquid measure or liquid capacity the basic unit is the gallon. Gallon is divided into 4 quarts, 8 pints, or 32 gills. The U.S. gallon, or wine gallon, is 231 cubic inches. The British imperial gallon is the volume of 10 lb of pure water at 62°F and is equal to 277.42 cu in. The British units of liquid capacity are thus about 20% larger than the corresponding American units.

Units of Dry Measure

For dry measure or dry capacity, the basic unit is the bushel. Bushel is divided into 4 pecks, 32 dry quarts, or 64 dry pints. The U.S. bushel is 2,150.42 cu in. and is about 3% smaller than the British imperial bushel with a similar difference existing between the U.S. and British subdivisions. The barrel is a unit for measuring the capacity of larger quantities and has various legal definitions depending on the quantity being measured.

VITRUVIAN MAN

The Vitruvian Man is a world-renowned drawing created by Leonardo da Vinci in 1487. The drawing, which is in pen, and ink on paper, depicts a male figure in two superimposed positions with his arms and legs apart and simultaneously inscribed in a circle and square. The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man. It is stored in the Gallery de Academia in Venice. The drawing is based on the correlations of ideal human proportions with geometry described by the ancient Roman architect Vitruvius in Book III of his treatise “De Architectura”. Vitruvius described the human figure as being the principal source of proportion among the classical orders of architecture.

According to Leonardo's notes in the accompanying text, it was made as a study of the proportions of the human body as described in Vitruvius:

· a palm is the width of four fingers;

· a foot is the width of four palms;

· a cubit is the width of six palms;

· a pace is four cubits;

· a man's height is four cubits (and thus 24 palms);

· the length of a man's outspread arms (arm span) is equal to his height;

· the distance from the hairline to the bottom of the chin is one-tenth of a man's height;

· the distance from the top of the head to the bottom of the chin is one-eighth of a man's height;

· the distance from the bottom of the neck to the hairline is one-sixth of a man's height;

· the maximum width of the shoulders is a quarter of a man's height;

· the distance from the middle of the chest to the top of the head is a quarter of a man's height;

· the distance from the elbow to the tip of the hand is a quarter of a man's height;

· the distance from the elbow to the armpit is one-eighth of a man's height;

· the length of the hand is one-tenth of a man's height;

· the distance from the bottom of the chin to the nose is one-third of the length of the head;

· the distance from the hairline to the eyebrows is one-third of the length of the face;

· the length of the ear is one-third of the length of the face;

· the length of a man's foot;

BIPM and CIPM

Recognising the need to work towards internationally agreed measurement standards, in 1875 governments from 17 countries worldwide signed the treaty and agreed to create and finance a permanent, scientific institute, the International Bureau of Weights and Measures as the centre for coordination of world measurement. The central coordination role for worldwide metrology is undertaken by the International Bureau of Weights and Measures with individual countries represented by National Metrology Institutes. The International Committee of Weights and Measures was established to oversee the International Bureau of Weights and Measures. Today there are 51 Member States of the Metre Convention. 23 Associate States take part in the General Conference of Weights and Measures.

BENEFITS OF ISO STANDARDS

For businesses, the widespread adoption of International Standards means that suppliers can develop and offer products and services meeting specifications that have wide international acceptance in their sectors. Therefore, businesses using International Standards can compete on many more markets around the world. For innovators of new technologies they speed up the dissemination of innovations and their development into manufacturable and marketable products. The worldwide compatibility of technology which is achieved when products and services are based on International Standards gives customers a broad choice of offers and insures quality, safety and reliability of products and services. They also benefit from the effects of competition among suppliers.

The technological and scientific bases underpinning health, safety and environmental legislation are provided by ISO standards for the benefit of governments. They are also an important source of technological know-how. By defining the characteristics that products and services will be expected to meet on export markets, International Standards give developing countries a basis for making the right decisions when investing their resources and thus avoid squandering them.

For trade officials, International Standards create “a level playing field” for all competitors on those markets. The existence of divergent national or regional standards can create technical barriers to trade. International Standards are the technical means by which political trade agreements can be put into practice. The International Standards contribute to the quality of life in general by ensuring that the transport, machinery and tools we use are safe and standards on air, water and soil quality, on emissions of gases and radiation and environmental aspects of products can contribute to efforts to preserve the environmen t.

GLOBAL COORDINATION OF METROLOGY AND THE CIPM

 

The reliability of the international measurement system depends on work by each national metrology institute to base its measurements and measurement uncertainties on the International System, and to compare its realizations of the base units of the IS with those of other national metrology institutes. To establish such mutual equivalence, the National metrology institutes will regularly participate in measurement comparisons.

In order to extend and fully document the practice of comparisons and to provide objective evidence on which to base declarations of equivalence, in 1999 the International Committee for Weights and Measures launched a Mutual Recognition Arrangement between National metrology institutes from Member States of the Meter Convention and Associate States and Economies of the General Conference of Weights and Measures.

The CIPM MRA establishes a formal system within which National Metrological Institutes signatories and other designated institutes establish the degree of equivalence of their national measurement standards via a peer-review of their technical capabilities, as well as the mutual recognition of their calibration and measurement certificates. This degree of equivalence is technically supported through a series of “key” measurement comparisons which establish a basis for comparing and linking measurements across international boundaries.

The CIPM MRA commits metrology to provide an essential support for global trade through a mutual recognition framework, which can help eliminate technical barriers to trade and regulatory affairs.

To support the CIPM MRA the International Bureau of Weights and Measures key comparison database provides free public access to the results of key comparisons and the peer-reviewed, IS traceable, calibration and measurement capabilities, and the degrees of equivalence of participating laboratories in many areas of chemistry and physics.

The launch of the CIPM MRA was a major step for the Meter Convention. As a result, metrology laboratories are now more confident of the technical basis for their calibration services, and their listing provides National metrology institutes with internationally recognized competence. It is already proving its value in the world of NMI metrology and a number of international and national organizations have already committed themselves to use it as evidence of technical equivalence at the highest levels, or for wider agreements negotiated for international trade, commerce or regulatory affairs.

Whilst the technical coverage of the CIPM MRA is presently focused on physics, engineering and chemistry, the future will see related developments in the areas of laboratory medicine and food as the established framework can be applied to these new sectors. Already in laboratory medicine, the Joint Committee for Traceability in Laboratory Medicine (JCTLM) is creating a similar database of reference materials and processes. Key and other comparisons are underway to help provide the technical underpinning for this work. In this way, sound metrology practice will be applied to new activities, which contribute to human health and the quality of life.
